Lagrange's Equations of Motion. Ball rolling down a wedge. Part (b).
มุมมอง 240ปีที่แล้ว
In this problem, we calculate the equations of motion of a ball that is rolling down a wedge without slipping. Also, we calculate the acceleration of the ball under certain conditions given by the problem.

Lagrange's Equations. The Spherical Pendulum.
มุมมอง 828ปีที่แล้ว
In this video we calculate the Lagrange's Equations of motion for a spherical pendulum. Also we calculate the equations of motion for this pendulum when it behaves like a simple pendulum and conical pendulum under certain conditions given by the problem.

hola, excelente video, una pregunta, de que libro es el ejercicio?

I solved it completely
The last part should have a positive potential V(r)
I dont fully get why y=h(t)-lcos(theta), instead of y=h(t)+lcos(theta). you state that h(t) is the long distance but i dont get that, since h(t) is just the movement of the support. Could you elaborate on that plz?
Because the origin of coordinates is where you measure the potential energy from, then the height of the mass is given by y = h(t) - L cos (ø) at any time. Hope this helps
I don’t think u can do (m+M) for T of wedge.
Only small m
Yes@@dhwdue8769
Hola, muchas gracias por compartir. Podrías indicar de qué libro proviene el problema que has resuelto? Gracias
Hola, Lagrangian and Hamiltonian Mechanics, M.G. Calkin.
Very good, question. Thank you!!
Thank you, teacher. Good explained!!!
Thanks
I still don't understand why V(system) = -mgysin(α)
I get your point, you consider V(ball) like that because you take your initial reference point the initial height of the ball. Hopefully this helps.
Also because the wedge is all the time on the floor, then you consider its center of mass potential energy like zero. If you want to take into consideration the dimensions of the wedge I think the problem would be much more complex. Hopefully this helps.
Got it, thank you very much for the explanation :D
You lost the "m" on the first term in the denominator (timestamp ~11:00) when you factored out "1/5m", but you have it there on the next rewrite.
Thank you for your consideration
Why didn't you cancel out the mass at the end?
You are right, thank you for your consideration
How can I do the solutions of those equatioons? Can you explain me ?
❤️
Very good and well explained video, however at 14:37 you write the potential as positive in your Lagrangian, where it should be negative as when you construct the Hamiltonian it results in a negative potential
Thank you for your consideration
LoL, thanking won't help bro. Pls correct it or put a correction note in comments.
did u solve this problem with newtonion ?kindly solve this
Thank you so much sir
🙏🙏
Awesome !
Thanks
Nice!!
Thanks!
Thank you very much for this video. I just wanted to ask, isn't it +2mgAx at the end, and not -2mgAx? I apologize if I am missing something.
Yes ,it is +2mgAx
Wich software do you use for writing?
I use a Samsung tablet, the App is called S note.
Sir can you please find the Lagrangian of a pendulum whose point of suspension is constraint to move on a parabola?
Yes I am trying to solve that one, I wil upload the video pretty soon
Thank you very much sir. I subscribed.
Thanks for the sub!
thank you very much
